WIRE-DRAWING- MACHINE.

Specification of Letters Patent.

Patented Aug. 15, 1911.

Commonwealth of Massachusetts, have in-' vented a new and usefulImprovement in 'Wire-Drawing Machines, of which the following is aspecification, accompanied by' drawings forming a part of the same, inwhich-' Figure 1 is a top view of a wire drawing machine embodying myinvention, and Fig. 2 is a sectional view on line 22, Fig. 1.

Similar reference lettersand figures refer to similar parts in thedifferent views.

My invention relates to an improvement in that class of wire drawingmachines in which the wire is drawn through several successive dies in acontinuous operation, and it consists in the construction andarrangement of parts as hereinafter described and pointed out in theannexed claims.

Referring to the accompanying drawings 1 denotes the framework of themachine in which is journaled ahorizontal driving shaft 2, provided withtight and loose pulleys 3, 4, and having bevel gears 5, 6 and 7 attachedto the shaft 2, Engaging the bevel gears 5 and 6 are bevel gears 8 and 9held on inclined shafts 10 and 11 journaled in the framework of themachine. The shafts 10 and 11 carry conical wire drawing capstans12and13 which are supported at a separate horizontal plane from theplane of the horizontal driving shaft 2 and are provided with the usualV-shap'ed circumferential grooves.

Supported on the framework of the machine between the capstans 12 and 13is the usual die box 14 provided with the customary dies placed inalinement with the circumferential grooves, in the usual manner. Theinclination of the shafts 10 and 11 is of such a degree that thetapering sides of the capstans stand approximately in horizontal andvertical planes and the bottom of the die box 14 is therefore horizontalto correspond with the horizontal surface of the capstans 12 and 13. Thedie box 14 is also supplied with a lubricating liquid from a trough 15below the capstans 12 and 13 by means of a pump 16 which forces theliquid through the pipe 17 into the die box 14, the overflow from whichis received in the trough 15." The capstan 13is provided with a drawingblock 18 and the usual swinging die holding bar 19 to assist in reducingthe end of the wire in diameter when it is strung upon the capstans. Thebevel gear 7 engages a gear 20 by means. of which the wire drawing block21 is driven.v

The operation of stringing the wire upon the wire drawing capstans atthe beginning of the operation of wire drawing is accomplished in theusual way, the-end of the wire being pointed and passed through thelargest of the dies placed on the swinging bar 19, and then wound uponthe block 18. As the size of the wire is reduced it is wound upon thecapstans 12 and 13 in the circumferential grooves and through the diesin the die box 14. The inclination of the shafts 10 and 11 by raisingthe capstans above the plane of the shaft 2, as has been described,brings the sides of the capstans into approximately horizontal andvertical planes, thereby greatly increasing the ease and rapidity of thewinding by the operator over the former methods of winding in wiredrawing machines of this class, in which the wire capstans are placed onhorizontal shafts in the same plane as the drivin shaft 2. By thisformer method the stringing of the capstans by the operator was alaborious and difficult matter, since considerable distanc'e separatedthe largest grooves in the capstans from the outside of the machine. Bymy improved method of mounting the capstans on inclined shafts, I bringthe lower side of the capstans approximately vertical at the front ofthe machine and within easy reach of the operator. I am also enabled tobring the upper surface approximately horizontal and I can thereforeemploy a die box whose bottom is horizontal, and the bottoms of eachsection in the same plane.

Beneath bases of the conical capstans 12 and l3-is an inclined apron 22over which the overflow of the lubricatingmaterial from the die box 14is conducted to the trough 15, through the trough 23. The inclination ofthe capstans causes the lubricating material to flow from the smallerends toward the larger ends of the capstans and be delivered upon theapron 22, thereby preventing the overflow from interfering with thehands of the operator in stringing the capstans.

I claim:

1. In a wire drawing machine, the combination of a pair of conical wiredrawing capstans having straight sides from the bottom to the top withcircumferential grooves, with the opposite sides substantially at anangle of ninety degrees to each other, and with the axes of saidcapstans inclined to bring the lower side vertical, thereby bringing allthe grooves of the capstan at the front of the machine.

2. In a wire drawing machine, the combination with a pair of conicalwire drawing capstans having straight sides from the bottom to the topwith circumferential grooves, said capstans mounted to bring the upperside horizontal, of a die box between said capstans with its bottomhorizontal, andmeans for driving said capstans, said capstans formedwith the opposite sides sub-. stantially at an angle of ninety degreesto each other, whereby the lower sides of said capstans, mounted withthe upper side horizontal, are approximately vertical, thereby bringingall the grooves of the the front of the machine.

3. In a wire drawing machine, the combination with the framework of themachine, of a pair of wire drawing capstans having circumferentialgrooves of gradually increasing diameter, with the smaller end of saidcapstans toward the front and with the upper side of said capstans inapproximately the same horizontal plane, a die box supported on saidframework between said capstans in a plane parallel with the plane ofthe upper side of said capstans, and means capstan at for driving thecapstans.

4. In a wire drawing machine, the combination with the framework of themachine, of a pair of wire drawing capstans having circumferentialgrooves of gradually increasing diameter and the smaller end of saidcapstans toward the front, said capstans having their axes inclined tobring the lower side toward the front, but with said inclinationarranged to bring the upper side of said capstans 1n approximately thesame horizontal plane, a die box supported on said said capstans arraned to bring the plane of the upper line 0 said grooves approximately thesame and'horizontal, of a die box in a corresponding horizontal plane,thereby allowing thefiow of liquid in said die box toward the front, andmeans for driving said capstans.

6. In a wire drawing machine, the combination with the framework of themachine, of a pair of conical wire drawing capstans with circumferentialgrooves, mounted on inclined shafts, a die box supported on saidframework between said capstans in one horizontal plane, with the planeof the upper side of said capstans arranged to correspond with the planeof said die box, thereby bringing the lower side of said capstans towardthe front. i

7 In a wire drawing machine, the combination with the framework of themachine, of a pair of conical wire drawing capstans with circumferentialgrooves, mounted on inclined shafts, a die box supported on saidframework between said capstans in one horizontal plane, with the planeof the upper side of said capstans arranged to correspond with the planeofsaid die box,

thereby bringingthe lower side of said capstans toward the front, and aninclined apron below the bases of said capstans to receive the overflowof lubricating material from said die box.
